Study on the Competition Status and Spatial Correlation of Medical Market in Beijing / 中国医院管理

ABSTRACT

Objective To analyze the competition status and spatial autocorrelation of Beijing medical market from 2015 to 2019.Methods The Herfindahl-Hirschman Index(HHI)was used to calculate the degree of market competi-tion in 16 districts of Beijing,and the Moran index was used to calculate the spatial autocorrelation of market compe-tition.Results Except for the number of discharged patients,the average HHI of the number of health technicians,the number of beds and the total number of medical visits in 16 medical markets in Beijing from 2015 to 2019 showed a downward trend between 0.2 and 0.4,and the spatial global Moran index of the HHI index was all less than 0,showing a spatial negative correlation with the degree of competition in the medical market.Conclusion The medical market competition in Beijing is strengthened,the competition gap between urban and rural areas is large,and the competition in adjacent markets is mutually exclusive.It is suggested to strengthen the differentiated develop-ment of hospitals,strengthen the balanced layout between regions,and promote the low-competitive market with cross-regional medical association,forming a positive spillover effect.
